So being told once what it was, I didnt have to decipher it again. A Truck Rollover Warning (W1-13) sign (see. The most common are those that never pull over in a passing lane they just carry on at whatever speed they were going in the center/middle lane ignorant of any traffic behind them. One on US Rt 1 is less than 1/4 mile long whats the point? Guidance: 03 The Merge sign should be installed on the side of the major roadway where merging traffic will be encountered and in such a position as to not obstruct the road user's view of entering traffic. The relative importance of the intersecting roadways may be shown by different widths of lines in the symbol. An Advance Traffic Control sign may be used for additional emphasis of the primary traffic control device, even when the visibility distance to the device is satisfactory. If the W11-2, W11-6, W11-7, or W11-9 sign is mounted overhead, the W16-7P plaque shall not be used. Vehicles should merge like a zip for the most effective traffic flow. You will also need to make sure that there is enough room between vehicles before you make your move into the traffic. Option: Any driver already familiar with a sign should be able to understand its meaning. First of all, signs are meant to be ubiquitous and learned by heart. The distances contained in. Standard: Standard: 07 Lane Ends signs should not be installed in advance of the downstream end of an acceleration lane. If used, the Advisory Exit Speed sign should be visible in time for the road user to decelerate and make an exiting maneuver. If used, the RIGHT (LEFT) LANE ENDS (W9-1) sign should be installed adjacent to the Lane-Reduction Arrow pavement markings. e.g. 03 The Chevron Alignment sign shall be a vertical rectangle. 01 The Playground (W15-1) sign (see Figure 2C-11) may be used to give advance warning of a designated children's playground that is located adjacent to the road. 07 When used, shoulder signs shall be placed in advance of the condition (see Table 2C-4).

If traffic can pass to either side of the obstruction, the alternating black and retroreflective yellow stripes (OM3-C) shall form chevrons that point upwards. It also employsa thicker line weight found on other W4-series signs. If used, a supplemental warning plaque shall be installed on the same post(s) as the warning or regulatory sign that it supplements. 02 These signs may be supplemented with an Advisory Speed plaque (see Section 2C.08). 1. Support: Option: 01 A horizontal alignment sign (see Section 2C.07) may be combined with an Advisory Exit Speed or Advisory Ramp Speed sign to create a combination Horizontal Alignment/Advisory Exit Speed (W13-6) sign or a combination Horizontal Alignment/Advisory Ramp Speed (W13-7) sign (see Figure 2C-1). When approaching the end of the passing lane, drivers in the right lane must merge safely with traffic to the left. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 99% Invisible Support: 05 The effectiveness of the placement of warning signs should be periodically evaluated under both day and night conditions. This designcan be mirroredto indicate a merge from either the left or the right. Figure 2C-10 Vehicular Traffic Warning Signs and Plaques. 08 The crossing location identified by a W11-2, W11-6, W11-7, or W11-9 sign may be defined with crosswalk markings (see Section 3B.18).

If the percent grade is displayed on a supplemental plaque, the plaque shall be placed below the Hill (W7-1) sign. In this design,the two main lines of the W4-2 arepushed together they come to represent lanes rather than boundaries of lane space. The DIP sign shall not be used at a short stretch of depressed alignment that might momentarily hide a vehicle. The distances are determined by providing the driver a PRT of 14.0 to 14.5 seconds for vehicle maneuvers (2005 AASHTO Policy, Exhibit 3-3, Decision Sight Distance, Avoidance Maneuver E) minus the legibility distance of 180 feet for the appropriate sign. Standard: You need to properly judge the time, speed, and space before your vehicle maneuvers into the other lane of traffic. Right-of-Way During Traffic Merges on Freeways Section 545.061 of the Texas Transportation Code states that a driver must yield to traffic on his/her left when entering a lane from the right, on a roadway divided into three or more lanes for one-way traffic. 03 Unless otherwise provided in this Manual for a particular plaque, supplemental warning plaques shall be mounted below the sign they supplement. 03 The Two-Way Traffic sign may be used at intervals along a two-lane, two-way roadway and may be used to supplement the Divided Highway (Road) Ends (W6-2) sign discussed in Section 2C.23.

The advisory speed displayed on the combination Horizontal Alignment/Advisory Speed sign should be based on the advisory speed for the horizontal curve using recommended engineering practices (see, The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Cross Road (W2-1) sign or the Side Road (W2-2 or W2-3) sign to create a combination Horizontal Alignment/Intersection (W1-10 series) sign (see, Elements of the combination Horizontal Alignment/Intersection sign related to horizontal alignment should comply with the provisions of, The use of the combination Horizontal Alignment/Intersection sign shall be in accordance with the appropriate Turn or Curve sign information shown in, A One-Direction Large Arrow (W1-6) sign (see, A One-Direction Large Arrow (W1-6) sign may be used to supplement a Turn or Reverse Turn sign (see. 01 A Merge (W4-1) sign (see Figure 2C-8) may be used to warn road users on the major roadway that merging movements might be encountered in advance of a point where lanes from two separate roadways converge as a single traffic lane and no turning conflict occurs. What is one-pedal driving in an electric car? The W11-1, W11-15, and W11-15a signs and their related supplemental plaques may have a fluorescent yellow-green background with a black legend and border. Guidance: 01 The SOFT SHOULDER (W8-4) sign (see Figure 2C-6) may be used to warn of a soft shoulder condition. Guidance: Guidance: When you drive a car, there are times where you will encounter two lanes merging into one. 02 On longer grades, the use of the distance plaque (W7-3aP or W7-3bP) at periodic intervals of approximately 1-mile spacing should be considered. However, these differences in engineering terminology are not well known by the public, so for signing purposes these terms are interchangeable. 01 A Divided Highway (W6-1) sign (see Figure 2C-5) should be used on the approaches to a section of highway (not an intersection or junction) where the opposing flows of traffic are separated by a median or other physical barrier. Option: Option: 01 The Low Clearance (W12-2) sign (see Figure 2C-5) shall be used to warn road users of clearances less than 12 inches above the statutory maximum vehicle height. Waiting too long can lead to your inability to pursue a claim and recover compensation for your damages. In this case, the signs dashes are shortened to dots and the dotted line is shifted more toward the center. 02 A Two-Way Traffic (W6-3) sign with an AHEAD (W16-9P) plaque (see Figure 2C-12) should be used to warn road users of a transition from a one-way street to a two-lane, two-way section of roadway (see Figure 2B-14). Thank you for articulating how the symbolism is different in these signs than other ones. Speed humps generally provide more gradual vertical deflection than speed bumps. As a stand alone, I think the sign is super unclear until I see it in a picture with the road. 04 Where conditions warrant, more than one marker, or a larger marker with or without a Type 3 Barricade (see Section 2B.67), may be used at the end of the roadway. It means your lane is about to disappear. At face value, C makes the most visual sense to me, but Id use the longer dashes from the current W4-2 instead of the dots.

Traffic separated by this sign may either rejoin or change directions. I think 6 and 8 both mean sharp curves, so why have 2 different signs?. 04 An UNEVEN LANES (W8-11) sign (see Figure 2C-6) may be used to warn of a difference in elevation between travel lanes. 03 Consistent with the provisions of Chapter 2L, changeable message signs may be used to display a warning message. No Parking (R8-3) signs should be placed near the ramp entrance. 03 If the access to the playground area requires a roadway crossing, the application of crosswalk pavement markings (see Section 3B.18) and Non-Vehicular Warning signs (see Section 2C.50) should be considered. The combination Horizontal Alignment/Advisory Speed sign shall only be used as a supplement to the advance Horizontal Alignment warning sign. Merging is where you join an existing lane of traffic or where two lanes become one. Type 1, 2, and 3 object markers are used to mark obstructions within or adjacent to the roadway. 05 Clearances should be evaluated periodically, particularly when resurfacing operations have occurred. Be prepared to adjust speed and always check your blind spot to avoid contact with another vehicle. I like B and C, but I think B encourages zipper merging more. PRODUCT ID: S (XXXX)W92 (L/R) (X)A (Y) Size (XXXX): (3636) 36" x 36" for use on Single Lane Roads/Multi-Lane Roads/Expressway Once you see that as a set of legs, theres no going back.

Guidance: By submitting a request for a free evaluation, I acknowledge that I understand and agree to the disclaimer and privacy policy. Option: 06 Warning signs that advise road users about conditions that are not related to a specific location, such as Deer Crossing or SOFT SHOULDER, may be installed in an appropriate location, based on engineering judgment, since they are not covered in Table 2C-4. Therefore they introduced huge diagrammatical signs, initially on motorways around the West Midlands but now theyre everywhere, on all classes of road: http://www.opsi.gov.uk/si/si2002/02311392.gif. The advisory speed shall be determined by an engineering study that follows established engineering practices. The One-Direction Large Arrow sign directing traffic to the right shall not be used in the central island of a roundabout. The use of the Chevron Alignment (W1-8) sign (see. Slow down and . If the curve has a change in horizontal alignment of 135 degrees or more, the Hairpin Curve (W1-11) sign may be used instead of a Curve or Turn sign. The equal spacing of the two lanes gives a much better visual of what is actually happening. The existence of text-only supplements (LANE ENDS MERGE LEFT) also suggests a graphic-only approach can be baffling. 03 Plaques with the appropriate alternative messages of TRAFFIC FROM LEFT (RIGHT) DOES NOT STOP or ONCOMING TRAFFIC DOES NOT STOP should be used at intersections where STOP signs control all but one approach to the intersection, unless the only non-stopped approach is from a one-way street. 01 The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Advisory Speed (W13-1P) plaque (see Section 2C.08) to create a combination Turn/Advisory Speed (W1-1a) sign or combination Curve/Advisory Speed (W1-2a) sign (see Figure 2C-1). 05 The Two-Direction Large Arrow sign should be visible for a sufficient distance to provide the road user with adequate time to react to the intersection configuration. A Merge (W4-1) sign with a NO MERGE AREA (W4-5P) supplemental plaque mounted below it may be used to warn road users on the major roadway that traffic on an entering roadway will encounter an abrupt merging situation without an acceleration lane at the downstream end of the ramp.

But not necessary if the driver was considerate. 01 A supplemental warning plaque (see Figure 2C-12) may be displayed with a warning or regulatory sign when engineering judgment indicates that road users require additional warning information beyond that contained in the main message of the warning or regulatory sign. Support: Option: For a single intersection, the name of the street to the left should be displayed above the name of the street to the right; or, For two sequential intersections, such as where the plaque is used with an Offset Side Roads (W2-7) or a Double Side Road (W2-8) symbol sign, the name of the first street encountered should be displayed above the name of the second street encountered, and the arrow associated with the second street encountered should be an advance arrow, such as the arrow shown on the W16-6P arrow plaque (see. 02 The Divided Highway (W6-1) sign shall not be used instead of a Keep Right (R4-7 series) sign on the approach end of a median island. 09-25-2007, 10:56 AM. 04 If the reason that the freeway is ending is that the next portion of the freeway is not yet constructed and as a result all traffic must use an exit ramp to leave the freeway, an ALL TRAFFIC MUST EXIT (W19-5) sign (see Figure 2C-5) should be used in addition to the Freeway Ends signs in advance of the downstream end of the freeway. Im one of those who can figure them out. 07 The Merge sign should not be used in place of a Lane Ends sign (see Section 2C.42) where lanes of traffic moving on a single roadway must merge because of a reduction in the actual or usable pavement width. 02 To provide additional emphasis, a Type 1 or Type 3 object marker may be installed at or near the approach end of a median island. Support: Option: A FREEWAY ENDS XX MILES (W19-1) sign or a FREEWAY ENDS (W19-3) sign (see, An EXPRESSWAY ENDS XX MILES (W19-2) sign or an EXPRESSWAY ENDS (W19-4) sign (see. One of the issues is matching the sign to other signs serving similar functions on roads (to increase its immediate legibility). The officer will investigate the crash and try to determine fault. They are much more rare in Maine than in NB Maine has its Interstates with divided travel lanes and even there lots of drivers dont understand fast and slow lanes. 02 The NEW plaque shall not be used alone. The Playground sign may have a fluorescent yellow-green background with a black legend and border. For Conditions A and B, warning signs with less than 6-inch legend or more than four words, a minimum of 100 feet should be added to the advance placement distance to provide adequate legibility of the warning sign. Where the clearance is less than the legal maximum vehicle height, the W12-2 sign with a supplemental distance plaque should be placed at the nearest intersecting road or wide point in the road at which a vehicle can detour or turn around. By showing you in advance how the roads join each other, the signs let you know when the road you are traveling on does not continue . I tagged this "Alberta, Canada" for you, since that is what your link says. The merging traffic sign will typically indicate which lane should be merging into the other. The Merge sign should not be used where two roadways converge and merging movements are not required. 14 A supplemental WHEN FLASHING (W16-13P) plaque (see Figure 2C-12) may be used with any Vehicular Traffic Warning sign that is supplemented with a Warning Beacon to indicate specific periods when the condition or activity is present or is likely to be present. 01 The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Cross Road (W2-1) sign or the Side Road (W2-2 or W2-3) sign to create a combination Horizontal Alignment/Intersection (W1-10 series) sign (see Figure 2C-1) that depicts the condition where an intersection occurs within or immediately adjacent to a turn or curve. Support: In situations where the condition or activity is seasonal or temporary, the warning sign should be removed or covered when the condition or activity does not exist. No border shall be used on the Chevron Alignment sign. The legend SPEED BUMP may be used instead of the legend SPEED HUMP on the W17-1 sign. 10 Because changes in conditions, such as roadway geometrics, surface characteristics, or sight distance, might affect the advisory speed, each location should be evaluated periodically or when conditions change. 03 The ROUGH ROAD (W8-8) sign (see Figure 2C-6) may be used to warn of a rough roadway surface. The minimum advance placement distance is listed as 100 feet to provide adequate spacing between signs. The Advance Traffic Control symbol signs (see. The categories of warning signs are shown in, Warning signs provided in this Manual cover most of the conditions that are likely to be encountered. Standard: 07 When used, Surface Condition signs should be placed in advance of the beginning of the affected section (see Table 2C-4), and additional signs should be placed at appropriate intervals along the road where the condition exists. When You Are Merging TRAFFIC CONTROL FOR SIGNALS ONLY PROJECTS ON 4 OR MORE LANE DIVIDED MAJOR ROUTES AND 4 OR MORE LANE MINOR ROUTES. 03 If used in front of a pier or obstruction, the Double Arrow sign should be mounted on the face of, or just in front of, the obstruction. Where there is a need to remind road users of the recommended advisory speed, a horizontal alignment warning sign with an advisory speed plaque may be installed at or beyond the beginning of the exit curve or on the outside of the curve, provided that it is apparent that the sign applies only to exiting traffic. Typical condition is the warning of a potential stop situation. However, in areas that experience changes in temperature causing frost action, a reduction, not exceeding 3 inches, should be used for this condition.

Standard: 04 If used, Chevron Alignment signs shall be installed on the outside of a turn or curve, in line with and at approximately a right angle to approaching traffic. This statute applies to lane changes as well as vehicles entering the roadway. If someone is pushing their way in, simply give them room. If two street names are used on the Advance Street Name plaque, the street names and associated arrows should be displayed in the following order: The CROSS TRAFFIC DOES NOT STOP (W4-4P) plaque (see. 634. Will it affect how it handles? If used, it shall be installed on the far side of a T-intersection in line with, and at approximately a right angle to, traffic approaching from the stem of the T-intersection. 05 A Pedestrian Crossing (W11-2) sign may be placed overhead or may be post-mounted with a diagonal downward pointing arrow (W16-7P) plaque at the crosswalk location where Yield Here To (Stop Here For) Pedestrians signs (see Section 2B.11) have been installed in advance of the crosswalk. ". The Divided Highway (W6-1) sign shall not be used instead of a Keep Right (R4-7 series) sign on the approach end of a median island. 01 Except as provided in Paragraph 2, a ROAD NARROWS (W5-1) sign (see Figure 2C-5) should be used in advance of a transition on two-lane roads where the pavement width is reduced abruptly to a width such that vehicles traveling in opposite directions cannot simultaneously travel through the narrow portion of the roadway without reducing speed. There are two kinds of drivers on merging roads.
